Hello, I have 2 kind of questions.
[1] Is there a reference for set Data Region & Cache configuration??
I don't know exactly how to configure data&Cache... so, I looking for
reference or best practice of cache&data region set up.
Is it normal case divide data region by domain/business purpose area??
[2] I have 3 nodes at remote server and I use java thin client in
application.
I found these error in log file.
how can i fix it? or is it not problem?
